UNITED STATES OLIVER H. HUMMEL, JIL, 0F HOT SPRINGS, ARKANSAS.

OINTMENT GI-IIRAIPRACTOR.

Application filed March 30, 1923.

To all whom it may concern:

Be it known that OLIVER H. HUMMEL, J12, a citizen of the United States,residing at Hot Springs, in the county of Garland and State of Arkansas,has invented certain new and useful Improvements in OintmentChiropractors, of which the following is a specification.

This invention relates to a machine for applying and rubbing inointment, liniment, etc., to the body of a patient, particularly theback of the patient and other parts of the body which cannot beconveniently reached by the individual efforts of the patient.

The primary object of my invention is to provide a machine adapted forapplying and rubbing in ointment, liniment, etc, to the body of apatient by the individual efforts of the patient, thus dispensing withthe use of a nurse or other attendant to apply ointment, liniment, etc.,to the back of a patient.

A further object of my invent-ion is to provide a machine of the abovestated character comprising a frame having a seat rest on which thepatient sits and levers pivotally mounted on the sides of the frameadapted to be connected to suitable means with a rubbing arm positionedon the rear of the machine, which not only enables the patient to fullyrub and massage his back, but also enables the patient to secure acertain amount of exercise by the operation of operating the handlescarried by the sides of the frame, the patient going through an exercisequite similar to that which would be necessary as in the act of rowing aboat, and as is a well known fact said form of exercise is consideredmost beneficial, as all muscles are brought into play when in the act ofrowing a boat.

A still further object of my invention is to provide an automaticointment applying and rubbing machine of the above stated characterwhich is simple in construction and operation, durable, eficient for thepurpose intended and one that can be manufactured and placed on themarket at a relatively low cost.

With these and like objects in View, my invention will be betterunderstood as the description proceeds and as is specifically pointedout in the appended claims.

Referring to the accompanying drawing which forms a part of thisspecification and Serial No. 628,794.

which clearly illustrates the operation and construction of my automaticointment applying and rubbing machine, 1

Figure 1 is a perspective view of same.

Figure 2 is a rear end elevation.

Figure 3 is a perspective view of therear end of the machine.

Figure 4 is an enlarged detail view of the ointment applying arm andrubber carried thereby.

Figure 5 is a detail view of a slightly modified form of buffer.

Figure 6'is a sectional view of the modified form of buffer.

Referring to the drawing in detail, like numerals will be used todesignate like parts in the different views.

The numeral 1 indicates a frame comprising a pair of side boards 22adapted to be closed at one end by ahead bar 8, and head posts 4: 4. areattached in any suitable manner to the side boards 22 at the front endof same. The rear end of the frame is adapted to be supported in a rigidposition by use of any suitable bracing means, and has positioned on thetop edge of the board 2-2 a seat rest 5. The side boards 22 are providedwith rollers 6 at each corner of the frame so that the -machine as awhole can be moved to any desired point.

Secured to the edges of the boards 2-2 at the rear ends are brackets orbearings 7 adapted to support therein a shaft 8 on which is adjustablymounted the lower portion 9 of an ointment and rubbing arm 10. The arm10 is'adapted to be connected with the lower half 9 of same by means ofthe pivot 11. The upper portion of the arm 10 is formed with a recessindicated by the numeral 12.

An ointment buffer 13 is pivotally connectedas at 14 to a staff 15,which is provided with a reduced portion 16 adapted to be received inthe hollow recess 12 in the arm 10, and to be securely locked therein bymeans of a set screw 17. The upper end of the upper staff 15 is providedwith a pair of arms 18, one positioned above the pivotal connection 14and one below same. The ends of the arms 18 are formed with eyes and areadapted to be connected with. the buffer 13 by means of coil'springs 19,said springs being adapted to hold the buffer in adjusted position toapply an ointment or liniment to the back of a patient, and at the Theshaft 8 projects beyond each side of the.

boards 2, and has keyed on each end a crank arm 23 adapted to bepivotally connected as iii) at 24 with a rod 25 that extends forwardlyon each side of. the machine and is pivotally connected as at 26 withoperating handles 27 said handles adapted to be mounted on each end ofthe shaft 28 that is supported by the boards 2'2. Coil springs 29.29 areeach connected at one end to the said handle 27 and at their oppositeends as at 30 to the head posts 4. Brackets '31 are keyed on the shaft8, one of said brackets being positioned on each side'ofthe, lower half9 of the arm 10 and coil springs 32 are connected at one end to ane eformed in thebrackets 31 and the opposite ends of each springare securedas at 33 to the inner wallsof the side boards 2. 7 'As it will benecessary to changethe cover of the buffer as same becomes soiled or anew" kind of ointment or liniment is used, I have provided a detachablecloth 34 that fits over'the buffer "13, and is secured on same by means"of a ring 35, so that as one clo'thbecomes soiled or unfit for use, thering 35 can be removed, the old cloth taken off and anew one replacedand then same locked in position by moving the ring over the buffer 13.

hen desiring to use my machine, the arm 10 is moved back into theposition shown in dotted lines in Fig. 1, after which the ointment orliniment is applied to the buffer 13 or cloth 34 as the case may be, andafter the patient has taken his seat within the machine, the arm 10, isbrought back to the position shownin full lines in Fig. 1, until thebuffer 13 rests against the back ofthe patient. Thus it will be seenthat; as the patient or operator of the machine draws the handlestowards the rear as shown 'indotted lines, the buffer 13 will becausedto movedownwardly under the influence of the spring 20, and by thepatient slightly shifting his position in the machine and allowing thecoil springs 29 and 32 to return the operating handle and arm 10 back toits normal position that the buffer 3 in returning to said normalposition will travel upwardly on the back of the'patient on a line ofpart of the body different from that covered on the downward'stroke:thusis can be seen that the machine not only fully applies an ointment tothe back and massages same, but also affords the patient a certain"amount of exercise 'by moving the handles 27 towards the rear againstthe tension of the springs 29 and 32.

- In view of the foregoing description of my invention taken inconnection with the accompanying drawing, it is thought that any furtherinformation as to the operation and construction of same areunnecessary.

While I have shown and described the preferred form of my invention, Irealize that various minor changes may be resorted to, without departingfrom the spirit and scope of the invention as claimed; therefore, I donot wish to limit myself to the exact details of construction shown, norto the combination and arrangement of parts.-
